Essentials
Wait for the lift to descend then step off it to enter a hallway with a shotgun, BFG9000, berserk pack, ammo pickups and a megasphere, which are guarded by an arch-vile. Open the north door to confront two more arch-viles then continue north through another door to enter a lava cave which is overlooked by two cyberdemons (as well as barons of Hell and yet more arch-viles on Hurt Me Plenty skill level or higher). Open the door under the cyberdemons and kill some demons, imps and a baron waiting behind it, then go through to a cross-shaped hub with a super shotgun and climb up the steps on the east and west sides to reach the surrounding ledge. Enter either tunnel on the north side of the hub and push past some imps to a bridge holding the blue skull key, which is protected by cacodemons.

Go back to the hub and open the west door (requiring the blue key) to get outside and find a rocket launcher guarded by Hell knights, barons and mutants. Press the gargoyle switch on the north-east wall to lower a lift at the south end, run to that lift to reach a second switch that lowers another lift to the north, then use that lift to reach a third switch that will lower one more lift near the first, which you can use to get inside the stone wall and confront some more mutants. Head north into a dark tunnel and follow it until you reach a ledge with a couple of revenants, then dispose of the knights on the neighboring ledge before running over to it to press a skull switch. Run through the south lavafall to get back outside, use the lift to get inside the stone wall again and head north into the tunnel - this time you can turn left to enter a room with a lava compass and four revenants. Press the skull switch here then go outside and kill any monsters you can see, including an arch-vile on the west ledge, before dropping into the lava and running south to a supercharge. Go through the nearby opening to enter a dark cavern with imps, then climb the steps on the north side to get the yellow skull key. Drop back into the lava and run straight forward to the north-east corner, which will raise some rock steps leading up to a fire portal that leads back to the stone wall.

Go back to the hub and open the east door (requiring the yellow key) to face imps, demons and revenants, along with a cyberdemon on an enclosed platform. Take the megaarmor in the lava pool then advance slowly up the curved stairs, which have more revenants on them, until you reach the top and see a baron in front of a skull switch - you must shoot the switch to raise a bridge, cross it then turn round to look at the cyberdemon's platform and shoot a second switch behind it to lower a pile of rocks blocking your path. Kill the demons and knights that were waiting behind the rocks then go east to a lift and kill the barons waiting at the top before riding it up to a door. Open the door to get a chaingun then continue north to a large lava pool containing imps and cacodemons - stick to the narrow paths by the walls whenever possible. Go to the south-east corner to find revenants guarding an eye switch, press it then go to the south-west end to find that a wall has lowered revealing an arch-vile. Step past this wall to find the red skull key, but watch out for a second arch-vile hiding behind the north wall as you approach it.

From the red key, drop down into the tunnel east of where you found the blue key, then go back to the hub and open the north door (requiring the red key) to find a skull switch - pressing it raises some steps on the other side of the lava, allowing you to climb up to another door. Open the door and kill an approaching arch-vile, then go down the steps to a hole that leads down to a blood pool with imps and lost souls. Go round to the enclosed area on the west side to find a revenant guarding a skull switch, press it to open the bars in the north wall then go through to the exit portal. The portal is defended by lost souls and demons, along with one to three arch-viles that teleport in as you go down the steps.

Secrets

 * 1) At the hub, take the west stairs up, then head left from the blue key door and slightly to the left of the fire cage on the southern wall. Press on the misaligned wall to reveal a room with two revenants and a switch, which lowers a lift. Take it up and collect the invulnerability for the secret. (sector 538)
 * 2) Open the blue key door and go through the lavafall. In the next area, run through the lavafall on the right to get a supercharge. (sector 564) The skull switch on the nearby platform lowers the bars in front of this item, allowing you to take the supercharge from the east if you want to collect it later; however, you must still walk through the lavafall to register the secret.
 * 3) Open the blue key door and use the nearby gargoyle switch, then run to the south-west lift. Ride it up and use the next switch, running directly north to the next lift, where this switch will lower a lift leading up to the bridge. At the top, head north into the corridor. At the northern-most bend, lower the north wall to get a megaarmor. (sector 567)
 * 4) In the lava compass room, press on the satyr block in the north-east corner to find large ammo pickups and a light amplification visor. (sector 569)
 * 5) In the room with the chaingun just before the large lava-filled area to the north-east, head east behind the dark gray brick walls for a radiation shielding suit. (sector 178)
